DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIG. 1, a triphase organic matter pyrolysis system 2 in accordance with the present invention comprises a feeding device 21, a preheating device 22, a steam (or vapor) generating device 23, a water ion generating device 1, a pyrolysis and carbonization reaction device 24, a heat recycle device 25, a gas-liquid separation (dissociation) device 26, a gas purifying device 27, a heater 28, and a controller 29.

The feeding device 21 delivers organic matters or compounds. Preferably, the organic matters include organic wastes of solid, liquid or gas phase that cannot be decomposed naturally and contain harmful substances, for example, sludge, sewage and waste gases. The feeding device 21 is used to deliver the sludge, sewage and waste gases that are to be processed.

The preheating device 22 is connected with the feeding device 21 to receive and preheat the organic matters of different classes. The preheating device 22 heats and evaporates the water in the organic matters previously or fills water into the organic matters that are too dry.

The steam generating device 23 fills and heats water to produce a saturated steam (or vapor) with a temperature of at least 130° C. to 160° C.

The water ion generating device 1 is connected with the steam generating device 23. The water ion generating device 1 receives and heats the saturated steam into a superheated steam which is dissociated and transferred into water ions.

The pyrolysis and carbonization reaction device 24 is connected with the preheating device 22 and the water ion generating device 1, to receive the preheated organic matters of the preheating device 22 and the water ions of the water ion generating device 1. The pyrolysis and carbonization reaction device 24 treats the water ions and the organic matters under an atmospheric (or normal) pressure and an anaerobic (or oxygen free) state by reactions of molecular scission, pyrolysis and carbonization, to form carbon residues (or dregs) and gas-liquid wastes.

The heat recycle device 25 is connected with the preheating device 22 and the pyrolysis and carbonization reaction device 24, to recycle and transmit a heat energy produced during operation of the pyrolysis and carbonization reaction device 24 and a residual heat energy of the gas-liquid wastes to the preheating device 22, so as to reduce an energy consumption of the triphase organic matter pyrolysis system 2. In the preferred embodiment of the present invention, the heat energy includes hot water or vapor at a high temperature.

The gas-liquid separation device 26 is connected with the heat recycle device 25 and the pyrolysis and carbonization reaction device 24, to receive waste water and waste gases that are separated from the gas-liquid wastes.

The gas purifying device 27 is connected with the gas-liquid separation device 26, and includes a spray tower 271 and a plasma treatment device 272.

The spray tower 271 is connected with the gas-liquid separation device 26, to receive and process the waste gases by a primary treatment, so as to eliminate acid/alkali, heavy metal, chlorine and carbon.

The plasma treatment device 272 is connected with the spray tower 271, to receive and process the waste gases after the primary treatment. The plasma treatment device 272 applies a high voltage (at least 20,000 to 30,000 volts) to decompose the waste gases, and to produce an electronic flashover which causes combustion, such that the waste gases are shocked electrically and decomposed by the plasma, and are burned in the space due to combustion caused by the electronic flashover. At this time, the plasma produces an O₃ reaction under high pressure and high temperature, such that the waste gases which cannot be burned are oxidated and decomposed by using O₃. Finally, the waste gases are drained outward when the waste gases cannot cause combustion any more.

The heater 28 is connected with the preheating device 22, the steam generating device 23, the water ion generating device 1, and the pyrolysis and carbonization reaction device 24 respectively. In the preferred embodiment of the present invention, the heater 28 is an electromagnetically heating device, wherein the interior of the pyrolysis and carbonization reaction device 24 will not produce flame during operation, such that the pyrolysis and carbonization reaction device 24 has an operational state with no open fires. In the electromagnetically heating device, the coil produces a magnetic field, with many eddy currents produced between the magnetic field and the metallic pipes or containers, such that the metallic pipes or containers produce the heat energy. The electromagnetically heating device is a traditional technology and will not be further described in details.

The controller 29 is connected with the heater 28, to control heating parameters of the preheating device 22, the steam generating device 23, the water ion generating device 1, and the pyrolysis and carbonization reaction device 24 respectively. Thus, the controller 29 preset working conditions (such as the heating time, the heating temperature or the like) of the heater 28 corresponding to the steam generating device 23, the water ion generating device 1, and the pyrolysis and carbonization reaction device 24 respectively. In addition, the controller 29 also monitors operations between the steam generating device 23, the water ion generating device 1, and the pyrolysis and carbonization reaction device 24, such as the circulation state and heat recycle state of the saturated steam and the superheated steam, the operation state of the pyrolysis and carbonization reaction device 24 or the like. It is appreciated that, the controller 29 may be a computer, a terminal, a server, a built-in system or the like.

In the triphase organic matter pyrolysis system 2 of the present invention, the superheated steam is divided or dissociated into water ions, including hydrogen ion (H⁺) and hydroxyl ion or hydroxide ion (OH⁻). Then, the organic matters are processed by molecular scission. Then, the organic matters are processed by carbonization to form carbon residues.

In practice, the feeding device 21 delivers the organic matters into the preheating device 22 to perform a preheating process. At this time, the water in the organic matters is increased or decreased. Then, the preheated organic matters of the preheating device 22 are delivered into the pyrolysis and carbonization reaction device 24. At the same time, water is filled into the steam generating device 23 which heats the water to produce a saturated steam of at least 130° C. to 160° C. The saturated steam of the steam generating device 23 is delivered into the water ion generating device 1 which receives and heats the saturated steam to produce a superheated steam which is dissociated and transferred into water ions. The water ions of the water ion generating device 1 are delivered into the pyrolysis and carbonization reaction device 24. Thus, the pyrolysis and carbonization reaction device 24 contains the preheated organic matters of the preheating device 22 and the water ions of the water ion generating device 1. The water ions and the organic matters are processed by reactions of ion exchange and molecular scission in the pyrolysis and carbonization reaction device 24. Thus, the water ions cut, dissociates and carbonizes the organic matters in the pyrolysis and carbonization reaction device 24 to form the carbon residues and the gas-liquid wastes. At this time, the interior of the pyrolysis and carbonization reaction device 24 will not produce flame during the pyrolysis process, such that the pyrolysis and carbonization reaction device 24 is disposed at an operational state with no open fires. In addition, the interior of the pyrolysis and carbonization reaction device 24 is under an atmospheric pressure and is disposed at a low oxygen content or an anaerobic state during the pyrolysis process.

The air in the pyrolysis and carbonization reaction device 24 and the hydrogen ion (H⁺) in the water ions produce organic waste water after the reactions of ion exchange and molecular scission. The organic waste water is then directly drained into a recycle tank 3. The heat recycle device 25 receives and absorbs the heat energy of the high temperature vapor and the decomposed waste gas of the pyrolysis and carbonization reaction device 24. The heat energy recycled by the heat recycle device 25 is delivered into the preheating device 22 for drying and heating purposes. The residual low temperature waste gas processed by the heat recycle device 25 is delivered into and processed by the gas-liquid separation device 26. The gas-liquid separation device 26 drains the condensed waste water into a recycle tank 3. The waste gas that is not dissolved in the water after the pyrolysis process is delivered into the spray tower 271. A flocculant is added into the spray tower 271 to process the waste gas (that is not dissolved in the water) by a primary treatment, so as to eliminate acid/alkali (by acid-base neutralization), sulfide, heavy metal, chlorine and carbon. The waste gases (such as alkane, lipid, ester, carbon oxide or the like) that cannot be treated by the spray tower 271 are delivered into and burned by the plasma treatment device 272, and are then drained outward from the plasma treatment device 272. Thus, the gas-liquid wastes are processed by the gas-liquid separation device 26 and the gas purifying device 27 to form gas and liquid that are harmless.

Referring to FIGS. 2-4 with reference to FIG. 1, the water ion generating device 1 of the triphase organic matter pyrolysis system 2 in accordance with the present invention comprises a connecting pipe 11, a heating tube 12, and a spraying head 14.

The connecting pipe 11 is connected with the steam generating device 23 which produces and delivers a saturated steam into the connecting pipe 11. The connecting pipe 11 has an interior that is penetrated (or perforated), and has a surface provided with a plurality of first holes 112 to enhance the surface area and to provide a temperature (or heat) storage effect.

The heating tube 12 has a first end connected with the connecting pipe 11 and has an interior provided with an air channel 121 which has a surface provided with an alloy catalyst layer 13. The heating tube 12 heats the saturated steam into a superheated steam with a temperature of at least 600° C. The superheated steam is dissociated and transferred into water ions by the alloy catalyst layer 13 of the air channel 121. The air channel 121 has a diameter (or volume) smaller than that of the heating tube 12.

As shown in FIG. 8, the air channel 121 includes a first passage 1211 and a second passage 1212. The first passage 1211 and the second passage 1212 intersect and partially connect to construct a cruciform or X-shaped structure. Thus, the air channel 121 enhances the contact area of the alloy catalyst layer 13 and the superheated steam.

As shown in FIG. 9, the air channel 121 includes a plurality of third passages 123. Thus, the air channel 121 enhances the contact area of the alloy catalyst layer 13 and the superheated steam.

The alloy catalyst layer 13 is formed on the surface of the air channel 121 of the heating tube 12 by electroplating, chemical plating, sputtering, deposition, coating, immersion plating or hot dip galvanizing. The alloy of the alloy catalyst layer 13 includes tungsten-iron alloy, tungsten-copper alloy, tungsten-nickel alloy, tungsten-manganese alloy, tungsten containing alloy, silicon-manganese alloy, manganese containing alloy or the like.

The spraying head 14 is connected with a second end of the heating tube 12, and has an interior that is tapered. The spraying head 14 is provided with a nozzle 141 which is connected with the pyrolysis and carbonization reaction device 24. The spraying head 14 has a surface provided with a plurality of second holes 142 to enhance the surface area and to provide a temperature (or heat) storage effect.

In practice, the steam generating device 23 is heated by the heater 28 such that the water of the steam generating device 23 is heated to produce a saturated steam which is delivered through the connecting pipe 11 into the heating tube 12 which heats the saturated steam to produce a superheated steam. The superheated steam is dissociated and transferred into water ions by the alloy catalyst layer 13 of the air channel 121. At this time, the alloy catalyst layer 13 performs a dissociation process to the superheated steam (H₂O) which is dissociated into hydrogen ion (H⁺) and hydroxyl ion (OH⁻). The water ions of the water ion generating device 1 enters the pyrolysis and carbonization reaction device 24 under an atmospheric pressure and an approximately anaerobic state.

Referring to FIGS. 5-7, multiple water ion generating devices 1 may be connected serially. For example, when two of the water ion generating devices 1 are connected, the spraying head 14 of one of the water ion generating devices 1 is juxtaposed to and inserted into the connecting pipe 11 of the other one of the water ion generating devices 1. Preferably, the nozzle 141 of the spraying head 14 of one of the water ion generating devices 1 is fitted into the connecting pipe 11 of the other one of the water ion generating devices 1 by interference fit or clearance fit. At this time, the first holes 112 of the connecting pipe 11 and the second holes 142 of the spraying head 14 are adapted for working holes of the interference fit or clearance fit.

The connecting pipe 11 has an interior that is tapered, and a connecting terminal 111 extends outward from the connecting pipe 11. The connecting terminal 111 of the connecting pipe 11 is connected with the steam generating device 23 (see FIG. 1). Thus, the multiple water ion generating devices 1 are connected serially, to enhance the speed of the water ions entering the pyrolysis and carbonization reaction device 24. At the same time, the heating tubes 12 of the multiple water ion generating devices 1 perform a multistage heating process, such that the heating tubes 12 heat the saturated steam into a superheated steam evenly.

Accordingly, the triphase organic matter pyrolysis system 2 and the water ion generating device 1 process triphase (solid, liquid and gas) wastes efficiently under the atmospheric pressure. The water ion generating device 1 produces water ions, and performs anaerobic pyrolysis carbonization reactions on the organic matters, to decompose and dissociate the organic matters step by step, so as to produce a final product, that is, the carbon. The decomposed substances of the organic matters are drained with the steam, and the final product is recycled into a safe inorganic matter, that is, the charcoal, so as to reuse the final product, and to achieve an environmental protection purpose.
